问题 I am trying to make an application with multiple users using SSE Emitter on React Native and Expo, so, for testing I need at least 4 expo connections in the same time. In this way, I used expo start on four terminal tabs and ran application in Web Browser. On the first three chrome tabs all works great, the request are fetching and sending valid data, but on the first one the requests are just pending. I thought it could be from CORS, cache control header, so I setted Cache-Control: 'no-cache

But as written in its documentation, it doesn't includes a feature with which user can select date and time together. This is the code given in their documentation: const showDatepicker = () => { showMode('date'); }; const showTimepicker = () => { showMode('time'); }; return ( <View> <View> <Button onPress={showDatepicker} title="Show date picker!" /> </View> <View> <Button onPress=

问题 Using expo, I need to provide a text-file with data (a word-dictionary) to the app. How do I provide that and how do I read it into memory? 回答1: I translated my textfile to a json-formatted content.

The json is parsed automatically. import data from './assets/woerter.json'; 来源： https://stackoverflow.com/questions/63104357/what-is-the-proper-way-to-bundle-a-textfile-with-the-app

问题 I'm running expo web build which uses react-native-web. I noticed it generates inline styles so if I render a list of items, the styles get repeated for each item. Is there a way to make it generate a unique className instead and add to the head like styled-components? 回答1: Revisited this and realized it's because the components I was using did not use the StyleSheet.create api call internally, which WILL generate atomic css classes on react-native-web. Setting a regular object as the style

问题 In all prev versions of Expo, I used RN fetch method to POST username/password to a Flask login endpoint. This endpoint saved user info to the session and set session cookie. It was always transparent and I never had to pass anything extra. This worked as of Expo v28. But when I upgraded to Expo 30, the server no longer sees the client as logged in.
